Application filed June 16, 1920. Serial No. 389,404.

To all'whom it may concern:

Be it known that I, CHARLIE M. Roenns, a citizen of the United States, residing at Mayo, in the county of Spartanburg and State of South Carolina, have invented certain new and useful Improvements in Roller- Pressurc Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a device for applying pressure to rollers, such as used in spinning machines for feeding and drawing the yarn, and aims to provide a novel and improved device of that kind constructed and arranged for distributing pressure between the rollers in a practical and efficient manner.

I he invention has for its object the provision of a device to bear on or against the journals or axles of a set of rollers, such as the feeding and drawing rollers of a spinning machine, and so constructed as to enable the pressure to, be distributed as desired to the rollers and adjusted to suit the needs.

A. further object is the provision of a device having provision for applying oil or other lubricant to the roller journals or axles on which the device bears. 7

It is also the object of the invention to provide such a device which is simple and inexpensive in construction as well as being thoroughly practical and efiicient in use.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and clalmed, 1t being un- 'derstood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is an elevation of the device as in use, portions being shown in section.

Fig. 2 is a plan view of the device straightened out and laid flat.

Fig. 3 is a reduced elevation of the device showing same opened up for assemblage with the stirrup bar.

As shown, the device is used on the feeding and drawing rollers of a spinning ma- ROLLER-PRESSURE I DEVICE.

groove 12 in its lowersur'face to fit on the axle 8 of the upper roller 7. A bearing bar 13 extends transversely over the axles 8 of the upper rollers 5 and 6, underneath the bar 10, with the forward end of the bar 13 adjacent to the head or bearing 11, and the rear end of the bar 13 connected by a knuckle joint 14 with the rear end of the bar 10, therebypivotally or hingedly connecting the rear ends of said bars. The bar 13 is provided in its lower surface with,

grooves 15 and 16, fitting on the axles of the upper rollers 5 and 6, respectively, and

the rear end-of the bar 10,-whilethe forward end of the bar 13 is pressed down by means of an adjusting screw 17,- or the like,

carried by the bar 10.near the head orbearing. 11 and contacting with the bar 13 near the forward end thereof. The pres sure is applied by the usual stirrup bar 18 of the spinning-machine which extends upwardly between the rollers 6 and 7, being provided at its upper end with a loop 19, and in uslng the present device, said loop the rear end of the bar 13 is pressed down by embraces the bar 10 immediately in rear of the bearing 11 and in front of the bar 13. The loop 19 can be readily engaged with the device, by straightening out the bars 10 and 13, as seen in Fig. 2, so they can pass through said loop after whichthe bars are folded together to seat on the axles, as seen 1n Fig. 1. The bar 18 is pulled downwardlyby a spring or weight (not shown) as well known in spinning machines, to ap- 7 ply pressure to the upper rollers.

With the present device, the pressure can be distributed to the upper rollers and ad justed according to the needs, by the adjustment of the single screw 17 Thus, when the screw 17 israised to relieve the flO pressure on the forward end of the bar 15, this will increase the pressure on the rollers 5 and 7, and decrease the pressure on the upper roller 6, whereas wh-enthe screw 17 is threaded downwardly to force the for ward end of the bar 13 down away from the bar 10, this will increase the pressure on the upper roller 6, and correspondingly decrease the pressure on the upper rollers 5 and 7, inasmuch as the screw 17 tends to raise the bar 10 when the bars are separated by the screw 17. It is thus possible to distribute and adjust the pressure, by the adjustment of the screw 17, to distribute the pressure to the several upper rollers, 5, 6 and T, as desired, and to enhance the feeding and drawing of the yarn.

The device is provided with means for the supply of lubricant to the grooves 12, 15 and 16, to reduce friction where the device bears on the roller axles. Thus, the bearing 11 has an oil duct 20 leading upwardly from the groove 12 and provided at its upper end with a funnel mouth 21 for receiving oil or other lubricant, and a wick 22 is disposed in the duct 20 forslowly feed ingthe lubricant to the axle of the upper roller 7.

The bearing bar 13 has lubricant ducts 23 leading upwardly from the grooves 15 and 16 to a longitudinal lubricant channel 25 in the upper surface of said bar, and a wick 24 has its terminals extending downwardly in the ducts 23, while the intern'iediate portion of said wick lies in the channel 25 tov convey oil or other lubricant from said channel to the grooves 15 and 16. In order to conveniently supply lubricant to the channel 25 and wick 24 the bar 10 has an oil hole 26 leading upwardly from its lower surface and having funnel mouth 27 at its upper end into which the oil can be poured,

so as'to flow down the hole 26 and drip therefrom into the channel 4E5 onto the wick 24.

The hinging of the bars 10 and 13 together also permits them to be swung apart, as seen in Fig. 3, to slip the bars endwise through the loop 19 of the stirrup bar, for assembling said bars, and when the stirrup bar 18 is in place adjacent to the bearing 11, the bar 13 is then swung back under the bar 10, which will retain the parts in place, the bar 18 being confined between the bearing 11 and end of the bar 18.

Having thus described the invention, what is claimed as new is 1. In a roller pressure device, the combination with a stirrup bar, of a pair of hingedlyconnected bars having bearing portions, the lastv named bars being arranged to swing apart for insertion through the stirrup bar and to be swung together to operative position for retaining the stirrup barand second named bars in place relatively to one another.

'2. A roller pressure device comprising in combination with a stirrup bar, a pair of hingedly connected pressure bars having bearing portions, said pressure bars being arranged to swing apart for insertion through the stirrup bar and to be swung together, one pressure bar having a portion beyond the end of the other for retaining the stirrupbar in place between the last named portion and last named pressure bar, and means between the pressure bars for adjusting them relatively to one another.

n1 testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses,

CHARLIE M. ROGERS.
